Parasitism is a common phenomenon in nature, where one species benefits at the expense of another. In marine environments, fungal parasites are known to infect phytoplankton, causing disease and death, and contributing to the loss of phytoplankton populations. The impact of fungal parasites on phytoplankton communities can be significant, as selective parasitism on one species of phytoplankton can encourage the development of other species and may be one of the factors influencing communities' seasonal succession. Fungi parasites play a crucial role in sinking by inducing cell death and promoting cell aggregation, which can lead to the export of phytoplankton to the deep sea. Although fungal parasites are well studied in freshwater phytoplankton, there is still little information on marine phytoplankton parasites. Recent studies have shown that large diatoms are the preferred hosts for fungal parasites in cold waters, while the infection of dinoflagellates is reported in the oligotrophic Mediterranean Sea. However, the occurrence and impact of fungal parasites on phytoplankton communities in the Red Sea remain largely unknown. Therefore, the proposed project aims to investigate the occurrence of fungal parasites that infect phytoplankton and analyze their role in the export of phytoplankton to the deep sea in the Red Sea. By understanding the ecological impacts, life cycle, host range, and infection strategies of fungal parasites on populations of Red Sea phytoplankton, this study can provide critical information on the dynamics of marine ecosystems and carbon cycling.

Knowledge about cetaceans in the Red Sea is limited with only a handful of sporadic or spatially-limited studies carried out to date. Funded by the Italian Cooperation through a Debt-for-Nature Swap programme and carried out in collaboration with the Egyptian NGO HEPCA, this thesis presents the results from the first ever systematic vessel-based surveys conducted in the southern Egyptian Red Sea from 2010 to 2013 using linetransect methodology. The main aims of the thesis were (a) to estimate cetacean abundance, (b) to determine distribution patterns and habitat use of the cetacean species, (c) to investigate movement patterns for species for which individual recognition techniques were suitable and (d) to identify areas of conservation concern for cetaceans with a particular focus on existing protected areas. Eight species were identified, of which five were commonly encountered (Stenella longirostris, S. attenuata, Tursiops truncatus, T. aduncus, and Grampus griseus) and three were rare (Pseudorca crassidens, Sousa plumbea, Balaenoptera edeni). Estimates of abundance using design-based line transect sampling techniques were obtained for five species: S. attenuata 10,268 (CV=0.26); S. longirostris 6,961 (CV=0.26); T. aduncus 659 (CV=0.69); T. truncatus 509 (CV=0.33), and G. griseus 367 (CV=0.37). Habitat modelling revealed that the two Stenella species were widely distributed across the study area. In contrast, T. truncatus was concentrated in waters around Ras Banas peninsula (in particular Satayah offshore reef), and T. aduncus was mainly found along the coast with possibly separate sub-populations in the northern and southern study area. G. griseus was only encountered in the southern part. The information provided in this study will allow the development of a conservation strategy for the protected areas and will serve as baseline information to carry out future survey work in the Red Sea.

Nowadays, the market environment is getting more radical and dynamic, such condition boosts up intensive competition make numerous organization toward red sea. Under such circumstance, however, the most important thing is not only to get survive but having additional earnings to sustain business. Thus lots organizations struggle to do renewal in strategizing, planning in order to differentiate themselves to outperform in their industry. Based on practical experience and integrate theoretical finds, the framework in analyzing how organization crafts sustainable capacity form coopetition(Äv¦X) is explored. Real practical case is illustrated in this study try to explain how L Company is integrated under a serious competitive condition and outperform then it shapes synergy from merging six parallel businesses into one big company. Through such merging story, finds are emerged as followings: 1. Small business can compete with big company by cooperation with others. 2. Relationship is critical element to integrate forces and accumulate common sense from business partners. 3. In integration, how effective result will come out through intensive compromising and negotiating among business partners. Keywords: Coopetition strategy, Red sea, Blue sea strategy, Zero-sum, Win-win.

Tourism has become one of Egypt’s main sources of income and has undergone rapid privatization and subsequent growth. This has resulted in numerous policy and implementation gaps including those in environmental policy. Egypt’s natural resources are thus threatened by this unsustainable tourism growth. This study analyses the impact of the tourism privatization movement in Egypt on the distribution of environmental responsibility between the private and public sectors and the environmental consequences. Changes in the roles of the private and public sectors in tourism and other roles, priorities, and agendas that each stakeholder may have are considered in this thesis. In order to gather information for this study, Egyptian laws and legislations pertaining to the areas of the environment, tourism and investment were examined. Secondary data from government sources about tourist numbers and characteristics, and about investment trends in Egypt were also obtained and examined. A series of interviews of key informants from the public sector, private sector, and NGOs were also conducted in the Egyptian capital city, Cairo, and on the Red Sea. Two Red Sea cities, Hurghada and El Gouna were visited and environmental initiatives in them were observed and made note of. This study finds that the Egyptian private sector is more successful than the public sector at planning and managing environmental initiatives, and that Egypt’s tourism pricing policy is a key influence on the level of environmental degradation. In terms of laws and regulations, it was found that Egypt has a sufficient number of environmental regulations and institutions; but that the challenge lies in their functioning and efficiency, and that the government’s environmental initiatives are largely symbolic and designed to attract foreign aid. These findings suggest that Egypt should focus on improving the quality rather than increasing the quantity of tourism. Accordingly, the marketing competitive advantage should be the quality and uniqueness of the destination rather than its low price. In terms of private-public sector interactions, governmental institutions should assume a more active role in environmental protection and should employ experts and knowledgeable professionals as decision makers, while the private sector should be encouraged to undertake large-scale tourism projects. It is found that sustainable tourism cannot be achieved without the contribution and collaboration of both parties in tourism planning and development.

Alors qu'elles n'intervenaient jusqu'ici que marginalement dans l'économie du pèlerinage à La Mecque (hajj), la catastrophe humanitaire constituée par l'épidémie de choléra de 1865-66 a conduit certaines puissances coloniales comme la France et la Grande-Bretagne, bientôt rejointes par l'Italie, à se saisir directement de la question de l'organisation des déplacements et du séjour de leurs sujets musulmans dans les Villes Saintes du Hedjaz. Pour la première fois dans l'histoire de l'Islam, le hajj a ainsi été supervisé par des puissances non-musulmanes. Si l'objectif affiché de l'intrusion européenne dans l'économie du hajj reste la protection sanitaire des pèlerins et partant du continent européen, il n'en cache pas moins des préoccupations plus politiques. L'enjeu est alors de rendre le hajj « gouvernable ». A cet égard, la Grande Guerre et l'annexion du Hedjaz par le gouvernement saoudien en 1925 constituent des étapes importantes en donnant aux puissances coloniales les moyens de construire de véritables « politiques du pèlerinage ». La décennie 1930 marque ainsi l'apogée de l'intrusion des puissances coloniales européennes dans l'organisation du pèlerinage à La Mecque qu'elles ont contribué à transformer en un instrument d'influence diplomatique et coloniale / While they intervened until then only marginally in the hajj affairs, the humanitarian disaster constituted by the epidemic of cholera of 1865-66 led colonial powers, such as France and Great Britain, soon joined by Italy, to deal directly with the question of the organization of the travels and the stay of their Moslem subjects in the Holy Cities of the Hijaz. For the first time in the history of Islam, the hajj was so overseen by not Moslem powers. If the official aim of european intervention remained the sanitary protection of the pilgrims - and, to a certain extent, the protection of the European continent - it hides not less more political concerns from it. Here the stake consists in making the hajj « governable ». In this respect, the Great War and the Hijjaz annexation by Saudi government in 1925 constitute important stages providing colonial powers the means to build of real « pilgrimage policies ». For the european colonial powers, the 1930's represent the peak of their intrusion in pilgrimage to Mecca organization they have contributed to turn into an instrument of diplomatic and colonial influence

Climate change poses a serious threat to species that demonstrate temperature dependent sex determination (TDS), including marine turtles. Increased temperatures can result in highly female skewed sex ratios and decreased hatchling success. In situ sand temperature data was collected from the nesting depth of hawksbill and green turtles at five study sites along the coast of the Red Sea. The sand temperature profile at four of the sites exceeded the pivotal temperature of 29.2°C (commonly cited in literature) throughout the study duration, which suggests feminization of turtles could be occurring, but further studies need to identify the pivotal temperature in this region. The percentage of days exceeding the commonly cited maximum thermal threshold (33 and 35°C) was calculated for each site at 30 and 50 cm. Sand temperature recordings were as high as 36.0°C at 30 cm depth, and 35.3°C at 50 cm. This suggests that the turtle hatchlings in some areas of the Red Sea could already have high mortality rates due to high temperatures, unless they are locally adapted to these high temperatures. The Red Sea is home to five out of the seven extant species of marine turtles in the world, but not much is known about these populations. The Red Sea is an understudied region of the world, but it has the potential to provide insight on how species might adapt to future climate change due to its high and variable water temperatures (range of 20°C to 35°C) and high salinity (40 PSU). Sites with lower sand temperatures (and lower risk of feminization) may represent priority areas for conservation efforts, particularly in regions facing imminent coastal development.

Masters of Science / A chemical study on the total extract of the zoanthid Palythoa tuberculosa, collected from the Red Sea, resulted in the isolation of seven polyhydroxylated sterols viz: palysterols A-G, six of which are new. Their chemical structures were elucidated on the basis of their 1D and 2D NMR and MS spectroscopic data. Palysterols B and G demonstrated cytotoxic activity on three human cancer cell lines (MCF-7, HeLa, and HT- 29). Palysterol G, in particular, was able to induce apoptosis in breast adenocarcinoma(MCF-7) cells

In 1938 Dr. Eugene Gudger concluded of the Red Sea that "whale sharks must surely abound in this region." Seventy years later, multi-method research began on a whale shark (Rhincodon typus) aggregation at Shib Habil, a reef near Al Lith, Saudi Arabia. However, in 2017 and 2018, a dramatic decline in encounters at this site drew questions about the aggregation's future and overall whale shark population trends in the region. In this dissertation, I describe and discuss the two-year decline in encounters and show that neither remotely sensed sea surface temperature nor chlorophyll-a concentrations were significantly different in seasons with or without sharks. Citizen science-based photo identification was used to characterize the northern Red Sea population, the Red Sea population as a whole, show limited crossover within the basin, and connections with another aggregation in Djibouti. Scarring rates within the Red Sea are compared to recent global studies, and the Red Sea uniquely had no predator bites observed, suggesting boat collisions are likely the leading cause of major scars. Finally, building upon previous genetic work comparing Red Sea and Tanzanian sharks using microsatellites, the mitochondrial control region was sequenced, and two global haplotype networks were produced and compared to each other and previous work. The stability of genetic diversity within the Shib Habil aggregation is compared to declines previously measured in Australia. As tourism develops along the northern Saudi Arabian coast and citizen science increases in the Red Sea, population dynamics within the region could be better understood. The genetic connectivity of Red Sea whale sharks to the Indo-Pacific population exemplifies the need for continued collaborative research beyond local aggregations and multinational conservation measures.
